Whitelist IP Address

Only if the transaction callback can get through your firewall and send you a transaction completion notification message.

To ensure that payment callback notifications are successfully received and not rejected by your servers, please take note of the following:

1. If your firewall or server configuration requires IP whitelisting for Codapay egress IPs, please send an email request to our support team at [e-mail]

2. Upon your request, we will provide you with the updated IP ranges or alternative domain/endpoint validation details required for your whitelist configuration.
